UNIVERSAL AIR-BLAST.

Specification of Letters Patent.

. Patented June 1t, 1915.

Application filed April 18, 1914. Serial No. 832,846.

To all whom it may concern Be it known that I, JACOB DIEHL, a citizen of the United States, residing at Glenbeulah, in the county of Sheboygan and State of Wisconsin, have invented a new and useful Universal Air-Blast, of which the following is a specification.

The present invention relates to an improved universal air blast, one object of the invention, being the provision of an air blast, whereby the air is properly'distributed through the fuel bed so that the articles being heated will be uniformly heated, thus imparting the desired uniformity of color or tempering thereto.

A further object of the present invention, is the provision of a universal air blast, composed of one or more units, each unit of which includes a raised chamber into which the gas and air is adapted to be forced, said chamber upon its upper surface being perforated so that the air and gas will be distributed uniformly through the bed of fuel.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a side elevation of the complete apparatus showing a portion of one air blast unit in section. V Fig. 2 is a view taken on line 22 of Fig. 1. F ig. 3 is a section taken on line 33 of Fig. 1. F ig. 4: is a perspective view of one of the units per 80.

Referring to the drawings, the numeral 1 designates the supports which carry the bed plate or table 2 and is provided with a plu rality of apertures 3 for the reception of the nipples l of the respective air blast members or units 5. These members 5, as clearly illustrated, are hollow and the upper surface is perforated as at a so that the gas or air supplied in said chamber is properly distributed through the entire surface ofthe member 5 into the fuel body. The upstanding walls 6 incase the member 5 on three sides so that the forward end is open for the in troduction of the fuel and for the articles to be heated. As shown in Fig. 1, the hoods 7 rest upon the upper ends of the partition 6 and thus constitute ovens with the fuel carrying member therebelow, this being of usual structure.

As shown in Fig. 2, a circular air blast member 5 is provided, the same having its upper surface provided with perforations a. It is evident that these members may be made in varying shapes and sizes as particularly illustrated in Fig. 2.

In order to properly supply gas and air to the respective units, a manually operated fan 8 is provided, the same commingling air with gas in the pipe 9 so that the same may be delivered through the respective upstanding valve controlled pipes 10 which lead into the respective units. By this arrangement, gas under pressure may be admitted to any one of the units or all as may be desired, the valves in the various connections 10 being manually controlled and in dependent of each other.

As illustrated in Fig. 4, these units may be made separate and may be used separately, as in blacksmith forges, the space between the partitions and about the perforated member 5 being filled with any form of carbon, such as bituminous or powdered anthracite coal or charcoal. It is also possible to use the same in connection with oil.

What is claimed is:

1. An air blast, having a fuel containing member, consisting of a base plate, three Walls upstanding therefrom at three sides thereof to form a receptacle open at one side and the top, the front edges of the two opposed walls terminating in alinement with the front edge of the base plate, and a hollow flat top projection carried by the base and having its edges spaced from the walls, said hollow projection being provided with a gas and air inlet through the bottom of the base, the surface of the top of the projection being perforated uniformly throughout its area for the even distribution of air and gas therefrom into the fuel body.

2. A universal air blast, including a base plate having a plurality of air blast directing openings therethrough, a plurality of hollow projections above the base plate and in. communication with the respective openings, there being one opening to each projection, and a plurality of upstanding walls carried by the base plate and providing a plurality of compartments or chambers one to each projection, there being a space bejection, aplurality of upstanding walls carried by the base plate and providing a plurality of compartments or chambers one to each projection, there being a space between the walls and the respective projections in each chamber and each chamber being open toward the outer edge of the base plate to permit of the introduction of fuel and articles to be heated therewithin, and a plurality of hoods supported upon the upper edges of the walls.

4. An air blast, having a fuel containing member, provided with three upstanding walls, and a perforated gas and air delivering flat top rectangular member disposed to provide a space between its sides and the walls.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

JACOB DIEHL.
